Sandblasting rooms

Powerful, flexible, adaptable and adjustable to any

application desired by the customer.

The field of application of our highly developed sandblasting rooms

runs from small-scale parts in large series to large workpieces, such as

ship components, vehicle parts and much more. The individual

workpieces are processed with a pressure sandblasting technique.

It is with large parts in particular, or when accessibility is problematic,

that the advantages of air blasting systems comes to the fore.

Over 150 built sandblasting rooms speak for themselves.

“Measuring up to your needs”

Our long years of experience in the construction of

sandblasting rooms becomes part of every new

project.

The requirements of sandblasting rooms are individually

implemented for every application. This is why it is essential

that we measure up: to your demands, to the local conditions

– because the solution we create for you must be sustainable

over the long term for every situation. The modern basic

concept of the plants and the variety of technical variants

ensure that all your goals can be realised.

Sandblasting rooms - Compact design, space-saving arrangement of all

ancillary components

- Powerful sandblasting grit transport with

efficient preparation

- Noise-reducing, dust-tight housings

- Environmentally friendly dust extraction and

filter technology

- Use of flexible transport systems for workpiece

transportation

- Low-wear, long-life components

Our sandblasting rooms are made to measure.

Thus, your requirements, such as technical conditions and local

particularities, can be taken account of to the greatest possible

extent. Room size is defined by workpiece dimensions and

offers the worker enough free space to work. Of critical

importance for the concept are, alongside the pure

dimensions, the definition of the blasting grit preparation,

ventilation-related aspects and peripheral operational and

safety aspects (number of doors, emergency exits, lighting,

wall and ceiling coverings).

Construction options The housing of the sandblasting rooms can be built of masonry

or steel with “sandwich elements”. Walls and doors are

provided with wear protection (thick special rubber). In the

design of the sandblasting room floor, various different

requirements can also be accounted for.

The leeway offered in design runs from simple sweeping pits

through partially evacuated sections to tried and tested high-

performance flat conveyor floors with grille covers for various

different loads. Here, the installation of rails and longitudinal

working trenches is also possible, offering the following

additional advantages:

- Low-noise operation

- Long service life

- Great conveying capacity

A traditional strength of our sandblasting room systems is in

the motor industry (lorries, buses) and carriage construction

(rolling stock, trams). The particular demands of these sectors

are accounted for in the plant concepts:

- Incorporation of lower work trenches or

entire floor

- Illumination of vehicle underside

- Transport platforms or blasting robots on

blasting room walls

- Extraction units for large blasting agent

quantities from blasted vehicle interiors

Blasting system Depending on the blasting room size and required area output,

one or more free jet pressure blowers can be used. The

sandblasting nozzles of our tried and tested free jet pressure

blowers are manually operated and can be fitted with an

automatic refilling system to ensure continuous operation for

the worker without interruptions.

Blasting grit recirculation To keep foundation costs as low as possible, space-saving flat

conveyor systems are used. In special cases, systems can also

be directly assembled on the floor of the industrial hall.

Transverse screw conveyors, or vibrating sieves in larger

systems, and bucket conveyors transport the blasting grit to

processing.

Carriage blasting

system - Carriage blasting system 33 m x 8 m x 8 m

- With 8 free jet sandblasting installations (4 each for ferrous

and mineral blasting agents)

- 2 lifting work platforms, moveable, swivelling.

- Complete blasting grit recirculation via flat conveyor floor,

sandblasting grit preparation with magnetic separator, dust

extraction system according to the circulation principle with

heat recovery, sandblasting room illumination with

additional lighting level.

- Raised rails for undercarriage processing with light carriage.

- Side moving platforms that can be swivelled out to reach all

surfaces.

- Extraction unit to extract the sandblasting medium in the

railway vehicles.

Blasting grit preparation

High quality requirements for blasted surfaces and

the deployment of reusable, recirculated

sandblasting grit make it necessary to separate out

contamination (rust, scale, old paint layers) and worn

sandblasting medium. To this end, we offer various

separation systems, depending on the application.

- Pneumatic separation, cascade wind sifter and

vibrating sieves offer defined quality and

guarantee the reusability of the treated blasting

grit.

- Using powerful magnetic separation systems, non-

ferrous metals and high-alloy steel can also be

processed to account the highest quality grades.

Dust extraction system The blasting result is critically defined by having the

best possible dust extraction. That is why we place

great value on suitably sized ventilation systems

which are designed for the best possible airflow.

To clean the dust-laden air, powerful dust extraction

systems in graduated series are used. Automatic

cleaning with pressurised air counter-flow ensures

continuous operation and constant air quality.

Thanks to low residual dust values, systems can be

operated in partial ventilation mode, also allowing

the plant to save energy during operation.

Thanks to our high production quality, you will

receive a sandblasting system with strong value

retention when resold, even after many years.

Sandblasting equipment in modular system

For optimal processing of the workpieces, in our

sandblasting rooms the use of all current

sandblasting grit is possible. These are recirculated

via several stages to the free jet pressure blower, are

processed and provided once again to the

sandblasting process at a constant working mixture.

This guarantees a high-quality result.

Example uses:

- Metal-processing industries

- Foundries

- Vehicle construction (road, rail)

- Ship-building, carriage construction

- Maintenance sector (reconditioning in varied

fields)

Air sandblasting systems offer maximum freedom

where workpieces of the most varied geometries are

processed.

This offers the following advantages:

- ideal impact of blasting medium

- Maximum blasting (no scattering

loss of blasting medium)

- The most efficient use of energy and

resources

The experts in blasting system construction and

maintenance works

For more than 45 years, blasting systems of the most diverse

kinds have been developed, constructed and manufactured for

the most varied uses in Großenlüder, including blasting rooms,

containers and cabins for injector blasting or pressurised air

blasting.

The experience gained in this period is reflected in our

standard products and special constructions. The core of our

business is always the high-quality implementation of our

customers’ requirements.

I, as a associat and managing director, began developing

everything to do with blasting during my apprenticeship at the

Großenlüder location and later in other companies.

That is why I took over the Großenlüder company and wish to

continue its work in the tradition of uniting customer demands

and their high-quality implementation.
